57AbstractABEin Verfahren und eine Anlage (10) zur Regelung eines kontinuierlichen Kristallisationsprozesses, der insbesondere zur Herstellung von Bisphenol A verwendet werden kann, weist eine mit einem Kristallisationsapparat (12) im Kreis geschalteten Wärmetauscher (14) auf. Eine Wärmetauscherleistung des Wärmetauschers (14) zur Kühlung eines Austrittsstroms (16) des Installationsapparats (12) wird in Abhängigkeit von einem zugeführten Feedstrom (24) eingestellt, um eine Austrittstemperatur des Austrittsstroms (16) zu regeln. Erfindungsgemäß wird die aktuell benötigte Wärmetauscherleistung rechnerisch ermittelt, wobei die errechnete Wärmetauscherleistung zeitlich gedämpft am Wärmetauscher (14) eingestellt wird. Durch die zeitliche Dämpfung werden große Temperaturunterschiede im Wärmetauscher (14) vermieden, so dass Fouling im Wärmetauscher (14) vermieden wird. Dies führt bei einer verbesserten Regelgüte zu weniger Produktionsausfällen und somit zu einer verbesserten Produktivität.
